IMPROVEMENT IN oRGAN-REEDS.

Specification forming part of Letters Patent No. 139,912, dated June 17,1873; application iled April 23, 1873.

To all whom it may concern:

Be it known that I, MILES (l. MORGAN, of Boston, in the county ofSuffolk and State of Massachusetts, have invented certain new and usefulImprovements in Reeds for Organs 5 and I do hereby declare that thefollowing tov be a full, clear, and exact description or' the invention,such as will enable others skilled in the art to which it pertains tomake aud'use it, reference being had to the accompanying drawings whichform part of this specification.

My invention relates to improvements in free-reeds for organs and reedinstruments, consisting in the employment of an additional plate overwhich the reed-block is made to slide. A clamp is secured to theadditional plate, between which and a projection on the lower plate thereed is clamped rmly. By movin g the reed-block between the said clampand projection the reed is shortened or lengthcned, whereby the reed isLeasily tuned without filing the reed, or by a movable clamp, asformerly done, as will now be more fully shown and described.

On the drawing, Figure l represents a front elevation of my improvement.Fig. 2 represents a central longitudinal section of Fig. 1, and Fig. 3represents a cross-section on the line A B, shown in Fig. 1.

Similar letters refer to similar parts wherever they occur in thedrawings.

a represents an ordinary organ-pipe, and a is the boot into which theorgan-pipe a is inserted. b represents the foot in the usual manner. cis the additional plate that may be attached to the organ-pipe a, or tothe boot a', by means of screws or solder, thus dispensing with thewooden echelott that was formerly used. The reed-block d is made toslide over the plate c, and is guided 4between the screws e e c c, ortheir equivalents, as shown in Fig. 1. The reed-block d is operated bymeans of a suitable rod, f, attached to the said reedblock, as shown inFig. 2. g is the reed that is clamped and held firmly in its upper endbetween a projecting' lip, h, made in one piece, with the plate c, asshown, and the lower end of a clamp, t', that is pressed against thereed by means of the screw 7c going through a slothole, l, in thereed-block d, and screwed in the additional plate c, as fully shown inFig.

2. The upper end of the clampi rests in a groove, m, made in the platec, as shown.

From the above it will be seen that the freereed g is clamped firmlybetween the lower end of the clamp i and the projecting lip h, made inone piece with the metallic plate c, and consequently no vibration ofthe reed g takes place above the place where it is clamped. The reed cantherefore vbe tuned easily simply by sliding the reed and reedblock d upor down, according to the desired pitch required. I shorten thevibrating' part ofthe reed g by moving the reed-block d upwards, wherebythe pitch is raised, and I lengthen the vibrating part of the reed bymoving the reed-block d downwards, whereby the pitch is lowered,according' to the height or depth of tone required. The reed can thus betuned at any time simply by moving the handle or rodf up or down,without removing the reed and block from the organ-pipe or reedboard.

All the parts of my invention are made of metal, and therefore notliable to get out of order.

This my invention is intended for what is called free-reeds-that is,reeds that are allowed to vibrate freely through the opening in thereed-block.

It is apparent to every one accustomed to tuning organ-reeds in theordinary manner,

`by ling the reed that this my invention is very simple and efficient,and that a great deal of labor is saved in tuning the reeds of organsand reed-instruments, having my improvement, instead of the ordinaryreeds now used.

Having thus fully described the nature, construction, and operation ofmy invention, I wish to secure by Letters Patent and claim- Incombination with the plate c, having a projecting lip, h, attachedthereto, the stationary clamp t', screw k, or its equivalent, and themovable reed-block d, for the purpose as herein shown and described.

In testimony that I claim the foregoing I have hereunto set my handthis14th day of April, 1873.
